A strikingly beautiful copper compound with the common name “blue vitriol” has the following elemental composition: 25.45% Cu, 12.84% S, 4.035% H, 57.67% O. Determine the empirical formula of the compound A 1.2569 g sample of a new compound has been analyzed and found to contain the following masses of elements: 0.7238 g C, 0.07088 g H, 0.1407 g N, 0.3214 g O. Calculate the empirical formula

2) lets take 100 g of the sample

Cu = 25.45 g = 25.45 g/ 63.546 g/mol = 0.4 mol

S = 12.84 g = 12.84 g / 32 g/mol = 0.4 mol

H = 4.036 g = 4.036 mol

O = 57.67 g = 57.67 g / 16 g/mol = 3.6 mol

The smallest number of moles is 0.4 and by dividing the individual moles with 0.4 we get the empirical formula

CuSH10O9

3) C = 0.7238g / 12g/mol = 0.06 mol

H = 0.07088 g/ 1 g/mol = 0.07088 mol

N = 0.1407 g / 14 g/mol = 0.01 mol

O = 0.3214 g / 16 g/mol = 0.02 mol

Dividing the individual moles with the smallest one 0.01gives the empirical formula
